Loop 101 and Loop 303 Freeways Close for Phoenix Weekend Construction

Several major freeway closures are scheduled in the Phoenix metropolitan area this weekend for construction and maintenance projects. The southbound Loop 101 between Princess Drive/Pima Road and Shea Boulevard in Scottsdale will be closed from Friday night through early Monday morning for a widening project, with detours via State Route 51 and Loop 202 recommended. Additionally, the Loop 303 in the West Valley will see northbound lane closures between I-10 and Happy Valley Parkway from Friday night to Saturday afternoon, and southbound lane closures over the following night into Sunday afternoon for pavement sealing, with Loop 101 serving as an alternate route. Drivers are urged to monitor real-time traffic updates through the az511 app or website and plan accordingly for detours. Meanwhile, in California, overnight lane closures on Interstate 405 through the Sepulveda Pass will cause significant delays Friday and Saturday nights as crews perform work, with motorists advised to seek alternate routes. Transportation officials emphasize caution in work zones and recommend allowing extra travel time due to these ongoing improvements.
